Computer shuts down after graphics card installation when under heaven load, however temperatures are not throttling, and are well within safe limits.

I built a computer 3 years ago, and a few months ago I installed a new graphics card (3060ti) It seemed to work fine for about a week or two and when I moved it, the problem began. This does not necessarily mean it was because of the movement of my setup but it could be. When I am playing games the computer seemingly "black-screens" the monitors show no signal while the computer lights stay on and fans stay running. I hear some audio but not all, and the computer usually restarts itself after a few minutes. I have closely monitored temperatures and GPU is safely around 70 Celsius under the heaviest load before it shuts off, and my CPU a mere 40-50 Celsius. The computer only shuts down when playing intensive games, but it has happened on rocket league which is confusing. It seems the more power that is drawn the higher chance it shuts off. I have well enough power in my power supply, a corsair 650 watt bronze 80+ with my 3060ti 6gb, i5 8600k and 16gb ram should have absolutely no problem from what I looked up. I have updated drivers, used different wall outlets, used different cables, checked for viruses, and fully cleaned my computer. There are a few other things I've tried but I won't mention because I may have not done a full enough job trying to fix it in that area. Is there any possible solution to my problem? I've scoured the internet for answers. 
Hi Flee. I'm Greg, awarded MVP for eleven years, Volunteer Moderator, and Independent Advisor here to help you until this is resolved.

1) If the card is new and within one year warranty period I'd contact the manufacturer's Support here: https://www.nvidia.com/en-us/support/ to get it tested and then if necessary RMA.

2) You can also test another graphics card which would eliminate all other causes if it works OK.

3) The Display driver is so important here that merely updating it is sometimes not enough. So let's try everything possible to get it working correctly:

First make sure you have updated the Display driver from the PC or Display adapter maker's Support Downloads web page for your exact model number, HP Serial Number or Dell Service Tag - from the sticker on the PC.

If necessary first remove the old driver using DDU (not necessary with Microsoft Basic driver which is a placeholder if nothing else is available) and/or installing in Safe Mode with Networking (so you have internet), or Safe Mode, accessed by one of these methods: https://www.digitalcitizen.life/4-ways-boot-saf...

While there check also for newer chipset, BIOS/UEFI firmware (very important), network, sound, USB3 and other drivers, comparing to the ones presently installed in Device Manager reached by right clicking the Start Menu.

If this doesn't give you the latest or ideal driver for what you need, compare it to the driver offered by the Nvidia Update utility here: http://www.nvidia.com/Download/Scan.aspx?lang=e...

For Display issues one fix that is working is to Roll back or Uninstall the Driver on the Display Device > Driver tab, restart PC to reinstall driver.

You can also try older drivers in Device Manager > Display device > Driver tab > Update Driver > Browse > Let Me Pick.

Then you will know you've tried everything in addition to Windows Update drivers.

Adjust the screen resolution until it fits and looks best at Settings > System > Display.

4) Troubleshoot random shut downs under load:

One of those should nail it. If you want to report back results as you go, I might have other suggestions.

Thank you so much for the extensive response, Greg. I have begin to try some of the things you recommended me, and will try my brothers RTX 3070 in one of the coming days. I just wanted to let you know I'm thankful for your response and also will get back to you once I try his card. Thanks.
